i HANDLE FOR PICKSANDqOTfiERTOOLS...

Application filed February 2e, sle. se Np. 7 2;

To all whom it may concern q Be it known that I, BENJAMIN BROGK- BANLK, a citizen of the United States, residing at Ramsay, in the county of Gogebic,

State of Michigan, have invented a new and useful Handle for Picks and other Tools; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

The invention relates to quick detachable handles for picks and other tools, wherein the necessity of quickly renewing the handle of the tool is necessary. For instance picks have to be resharpened and therefore it is necessary to remove the pick, from the Wooden handle for the reason that the pick points cannot be heated in a furnace while the handle is in the same.

A further object of the invention is to provide a detachable handle for picks so that they may be quickly detached from the picks, thereby eliminating extra labor wherever a large quantity of picks are in use, for the reason that one man can handle a greater number of picks between the resharpening shop and the working gang.

A further object of the invention is to provide the end of the pick handle with a tapering sleeve for the reception of the socket of the pick, also to provide the tapered sleeve with spring lug means whereby,

when pick socket is in place the spring lug will prevent the longitudinal movement of the pick on the handle, said spring lug being so constructed from the body of the tapered sleeve that it can be bent inwardly for releasing the pick head said bending being accomplished by means of a tool inserted in slots of the tapered sleeve.

With the above and other objects in view the invention resides in the combination and arrangement of parts hereinafter set forth, described and claimed, it being understood that changes in the precise embodiment of the invention may be made within the scope of what is claimed, without departing from the spirit of the invention.

j lteferringfto the drawings thenumeral 1 deslgnates a pickhandle, which may bemade o Wood o a any other uitable. m teri however this handle is preferably tapered. Secured by means of a bolt 2 to the enlarged tapering end 3 of the handle 1 is a tapered sleeve 4 which telescopically fits over the end 3 of the handle 1. The sleeve 41 is adapted to fit over the end of the handle and when the bolt 2 is removed said sleeve will easily slide over the small end of the tapering handle so that the sleeve may be removed from the handle when desired.

The sleeve 4 is made of metal and is tapered, it is also preferably oval in cross section to conform as near as possible to the shape of the conventional form of pick handle. One of the sides of the sleeve 4 is provided with a longitudinal slit 5, which slit 5 allows an expanding action at the end of the sleeve when a conventional form of pick head 6 is forced on the same, said tapered sleeve fitting into the pick head socket 7 This expanding action is great enough to bind the pick head on the sleeve, but at the same time the end of the sleeve will not contract to such an extent as to allow the pick head to slide off the end of the sleeve when the pick is in use.

One side of the tapered sleeve is provided with a V-shaped notch 8 thereby forming a spring tongue 9, said tongue having its end bent outwardly as at 10 thereby forming a locking means, which when in engagement with the pick head, as shown at 11 positively locks the pick head on the sleeve and prevents the same from sliding off the tapered sleeve and handle. a

When it is desired to remove the pick head from the handle for resharpening, it will only be necessary to remove the bolt 2 and then the sleeve 4: will slide over the handle 1. However when it is desired to remove the sleeve, it will only be necessary Specification of Iietterslatent. Sept. 16,1919.
